Memory
An overview of the individual memory areas and their use is contained in Chapter
3.7.6.
The following tables should contain incomplete address areas. Non-executed
addresses shall not be used for programming. They are either reserved for internal
use by the PROTECT-PSC or are not defined. A reading process of these ad-
dresses provides an unforeseeable state.
Communication with the gateway
Communication can be set up to a gateway additionally connected to a CPU
module for non safety oriented tasks (see Chapter 3.7.6)
. The ‘EL’ memory area is
used for data exchange. It occupies the EL000-EL07FF addresses.
The assignment of the ‘EL’ memory area breaks down as follows:
Gateway
Direction
PS
EV E00 - EFF (BIT)
EL 000 - 0FF
(BIT)
EV F00 - FFF (BIT)
➔
EL 100 - 1FF
(BIT)
S 140 - 14F (WORD)
EL 200 - 2FF
(BIT)
S 150 - 15F (WORD)
➔
EL 300 - 3FF
(BIT)

The EL400-EL7FF address area is freely available to the programmer and can be
used, for example, for markers which are not safe.
The delay time of the PROTECT-PSC for the transmission of the EL data area is
47.8 ms.
Communication between PS and PN
The EM (000..7FF) memory area is available for the operational communication
between the PS and the PN program.
